The solar system is a battlefield. From Mars' red deserts to the steaming jungles of Venus, conflict rages. From the huge caverns of the Mercurian underworlds to the cold hells of the Asteroid Belt, battle lines are drawn. The five great mega-corporations make war with each other. The fanatic soldiers of the Brotherhood clash with the undead warriors of the Dark Legion, who, in the name of their demonic masters, seek to conquer all who live. There is no peace. There are only small gaps between the wars, when the combatants seek to rebuild their strength before another cataclysmic clash with their eternal enemies.

Warzone is a two-player wargame set in the universe of Mutant Chronicles.
